Asp.Net实现论坛楼层功能

 <asp:Label ID="Label2" runat="server" Text="Label" ForeColor="Red"></asp:Label><%--显示第几楼--%>

 protected void DataList2_ItemDataBound(object sender, DataListItemEventArgs e)
        {
            int floorid = 1;//第几楼

            Label Label2 = (Label)e.Item.FindControl("Label2");//先找到用于显示楼层的Label控件

            if (e.Item.ItemIndex != -1)//默认的是-1
            {
                if (this.Label3.Text == "1") //分页的页数（第一页永远是从楼主开始的）
                { 
                    floorid = e.Item.ItemIndex + 1; 
                }
                else
                {
                    floorid = (e.Item.ItemIndex + 1) + ((int.Parse(Label3.Text) - 1) * 6);//每页显示几条数据就乘以几
                }
                if (floorid == 1)
                {
                    Label2.Text = "<a name=\"" + floorid.ToString() + "\"></a><font color=\"red\">楼 主</font>";
                }
                else
                {
                    Label2.Text = "<a name=\"" + floorid.ToString() + "\"></a>第 <font color=\"red\"><b>" + floorid.ToString() + "</b></font> 楼";
                }
